description

The SN74ALB16245 is a 16-bit transceiver

designed for high-speed, low-voltage (3.3-V) V

operation. This device is intended to replace the

conventional transceiver in any speed-critical

path. The small propagation delay is achieved

using a unity-gain amplifier on the input and

feedback resistors from input to output, which

allows the output to track the input with a small

offset voltage.

This device can be used as two 8-bit transceivers

or one 16-bit transceiver. It allows data

transmission from the A bus to the B bus or from

the B bus to the A bus, depending on the logic level

at the direction-control (DIR) input. The

output-enable (OE

) input can be used to disable

the device so that the buses are effectively

isolated.
